That thy trust may be in the Lord,.... By means of the words of the wise, or doctrines of the Gospel, faith in Christ is first had; men are directed and encouraged hereby to believe in him; and by the same means faith is increased, confirmed, and established.
This is the end of penning the Scriptures, and of the Gospel ministry, as follows:I have made known to thee this day, even to thee; the said words and doctrines in the ministry of the word, by the Spirit of wisdom and revelation in the knowledge of them; giving not only a notional, but a spiritual and experimental knowledge of them.
